Application filed November 9, 1906- fi fl 342,701.

To all whom it may concern: Be it known that 1, JOHN HENRY PruLLrPs, J12, a

. citizen of the United States, residing at the city of Jackson, county of Jackson, and State of Michigan,

adapted and, as shown herein, is designed fonuse as a,

. coupling for the steam and air pipes of railway trains,

- is clearly illustrated "in the accompanying drawing,

. .forming a part of this specification, in which,

although it is applicable and desirable for use in various other relations.

The objects of this invention are, first, to provide an or uncouple all of the pipes of a train, both steam and air, upon the coupling or uncoupling of the cars. Third, to provide an improved coupling for the pipes of railway trains, in which a car having a combined or combination coupling may be readily coupled or connected to a car equipped with individual couplings. Fourth, to provide a coupling for the steam' and air pipes of railway trains by which the use of rubber hose is dispensed with. Fifth, to provide an improved pipe or hose coupling which is very durable in use and one which is comparatively simple and economical in structure and very convenient in use.

Further objects, and objects relating to structural details, will definitely appear from the detailed de scription to follow.

l" accomplish the objects of my invention by the devices and means described iuthe following specification. The invention is clearly defined andpointed out in the claims.

- A structure embodying the features of my invention ing to line 4-4 of Fig. 3, showing structural details of" one ofthe connecting links for the coupler head to the rear plate of the frame. Fig. 5 is an enlarged detail section thereof, taken on a line corresponding to line 5-5 of Fig. 3, showing details for the connections for these links to the heads. Fig. 6 is a detail section taken on a line corresponding to line 6-6 of Fig. 3, showing the coupling lips of the coupling members. Fig; 7 is an enlarged detail longitudinal section through one of the joints for the pipe sections 32. Fig. 8 is an enlarged detail section taken on a line corresponding to line 8-8 of Fig. 3, showing details of the engaging members of the couplings. Fig; 9 is an enlarged detail taken on a line corresponding to line .99 of Fig, 8, showing the arrangement of the drain valve 30. Fig.

10 is a detail section taken on a line corresponding to line 1010 of Fig. 2, showing an individual coupling attached to the main coupling. Fig. 11 is a detail side elevation of a modified form of the individual coupling,

a pair of individual couplings being shown connected. Fig. 12 is a front elevation, corresponding to Fig. 2, of a modified construction, the coupler head. being supported entirely by springs and connected to the train pipes by rubber hose instead of the flexible pipes made up of sections. 1

In the drawing, the sectional 'views are taken looking in the direction of-the little arrows at the ends of the section lines, and similar reference characters refer to similar parts throughout the several views.

. Referring to the drawing, 1-l represent the frame of a railway car. On the under side of this frame is a longitudinal bar 2, having a cross-piece 3 at its forward end. At the rear end of the bar 2 is a vertically arranged rear plate 4. This plate is preferably braced from the bar 2 by the braces 5. The coupling head 15 is connected to this'plate by a pair of links. These links are preferablymade up of sections 7 and 8, the sections 8 being telescopically arranged within the sections 7. The ends of the sections 8, which telescope within the sections 7, are provided with longitudinal grooves 9 in which the set screw '10 engages This serves to limit the longitudinal adjustment or movement of the sections upon each other and secures them together. The coiled springs 21, arranged upon the sections 8, hold the same normally forward, the rear ends of the springs engaging the ends pf the link sections 7, and the forward ends engaging collars20 which are adjustably secured upon the sections 8. v I

The forward ends of the link sections 7 are provided with suitable balls l2 arranged in suitable sockets on the head 15. The rear link sections 7 are provided with balls 6 which are arranged in suitable sockets in the rear plate 4. These links are preferably arranged to diverge forwardly, yieldingly holding the coupler head forwardly and in alinement with the plates 4. The head 15 is provided with rearwardly and outwardly projecting'arms 16 having holes therein through which the links are arranged; see Fig.5. To these arms 16 is secured an inverted yokelike supp'orting frame 17; see Figs. 2 and 3. Weights 27 are connected to the coupler head by chains 24 arranged over suitable pulleys 25 on the. frame I. to normally hold the coupler head, the same being shown in ils lower position.

coupler head, its downward movement being checked by the chain 22. coiled spring 23. Buffer springs 26 are provided for the weights 27. the springs'being arranged on the chains 24. On each coupler head, at one side of the head block 13, is a conical rigidlatch 18 having a hook 19 at its outer end. On the other side of the head block is a conical socket 14 with an opening through the inner end thereof, adapted to receive the hook portion of the latchlS, the socket of one head plate being adapted to receive and latch the other. The conical socket is slightly flattened at. its inner end to permit a slight rocking of the latch therein, so that by tilting the heads rear wardly the latch is disengaged. These latches and berstogether, and, as the coupler heads are held normally outward by their supporting arms, the pressure of the coupler heads against each other forces them downand in contact; The coupling block' heads are prowardly to the position indicated in the drawings, in which position the head blocks are brought face to face vided with coupling lips 35 which are in contact when the heads are in this position. The details of these coupling lips are not here pointed out, as they are'de scribed in detail and claimed in the co-pending application filed concurrently herewith. When the cars are uncoupled, the'pressure of the coupler heads is released, so that they are elevated by the weights 27. At a certain point in this upward movement, the heads are rocked or tilted rearwardly, breaking the contact of the coupling blocks and disengaging the latches. This is preferably accomplished by passing the through the openings in the arms 16 of the coupler head, as described. The links epgaging the arms tilt the heads, as will .be readily apparent. The head blocks are preferably provided with a plurality of couplings proper 35,

which are arranged in a vertical series.

The coupler heads are connected by flexible pipes or hose to the steam and air pipes 36 of the car. These flexible pipes are preferably made up of sections 32 connected by -ball-and-socketjoints, the ball-andsocket joints preferably consisting of a socket 33 and a ball 37. The joints are provided withpackingrings 34 which are seated in thesocket 33 and are provided with a yielding flange-like portion 37, adapted to bear against the ball. These rings are preferably made of thin metal, so that they yield under the pressure of the steam or air and are held in position thereby, forming a perfectly tight joint. To insure contact when the steam is turned on springs 38 are provided. At the same time, thepressure and binding effect thereof is not sufficient to be objectionable. When-the steam 'is off, as is the case where the greatest movement of the joints takes place, the parts move very freely and with a. minimum wean, By thense of a'flexible pipe The 'weights 27 are sufficient l Stops 29 are provided for g the chains 2-4 to limit the upward movement of the At the u )er end oi this chain is a in this relation formed ofsections, as shown and dethat a more durable structure is secured.

in the structure. illustrated, I have shown the coupling adapted for the steam and air brake and air whistle. To arrange the structure for use in connection with the couplings having individual coupling members 38, I provide the head blocks 13 with sockets 31 adapted to receive the latches 39 of the individual coupler members. These catches are so arranged that they effectively guide the coupler members into proper position to bring the lips thereof together. These indiinto place by hand. 7

I have illustrated in Fig. 12 a modified construction, in which the coupler heads are supported entirely by springs 40 and 41. The suspending frame 42 in this construction has depending arms at each side so that heads in 'a central position. The rear plate and supporting arms are in this construction'omitted and rubfor use as a coupling for the pipes of railway trains, and I have illustrated the same adapted for thatnse,

plicable, for use in other relations. v

In the modified construction, the'upper pairof supporting arms 42 are arranged to tilt the-coupling members swing upwardly when released, is reversed and the engaged members readily disEhgageI In addition to this, a greater amount of steam or air pressure being below the'center line of the guide arms tends to hold them more securely'in their'engaging position as more pressure is added. I

.My improved hose orpipe coupling is adapted to cure joint, and one which is practically impossible to become detached without uncoupling the cars. While I have illustrated the same as a combination coupler, that is, a coupling for a plurality of pipes, it is-evident that it might 'be adaptedfor a single pipe.

ling in detail in the form preferred by me onaccount of its structural simplicity and economy and convenience in use. -I am aware, however, that it is capable of considerable variation in structural details without departing from my inyention, and I desire to be under stood as claiming the same specifically as is herein illustratedas well as broadly. 1
